Tassili n’Ajjer (10.000 a.C.): il museo a cielo aperto dell’arte rupestre sahariana
Nel cuore del Sahara algerino si alza un altopiano di pietra arenaria dall’aspetto lunare, dove gole e formazioni rocciose custodiscono uno dei patrimoni figurativi più straordinari dell’umanità: oltre 10.000 incisioni e pitture rupestri che mostrano come il Sahara, una volta verde e abitato, si sia trasformato nel deserto più grande del mondo. Il Tassili n’Ajjer è Patrimonio UNESCO dal 1982, come sito misto naturale e culturale.
At a glance
Tassili n’Ajjer (“Plateau of the rivers” in Tuareg) is a vast mountain range of sandstone in south-eastern Algeria, covering more than 72,000 km². It contains one of the world’s most important concentrations of prehistoric rock art: over 10,000 identified engravings and paintings, dating from approximately 10,000 BC to the first centuries AD. The art documents the “Green Sahara” period — when the region was wetter, forested and populated by elephants, rhinoceroses, hippopotamuses and cattle herders — before the progressive desiccation of the last 4,000 years. UNESCO inscribed it in 1982 as a mixed natural and cultural site.

- Area: over 72,000 km² in south-eastern Algeria
- Rock art: more than 10,000 paintings and engravings, dating from 10,000 BC to c. AD 100
- Green Sahara: depicts elephants, rhinos, hippos, cattle — evidence of a wetter past
- Mixed site: inscribed for both cultural (rock art) and natural (unique geological formations) value
- Tuareg: the plateau is the homeland of the Tuareg people; the name means “plateau of the rivers”
History
During the African Humid Period (roughly 11,000 to 4,000 years ago), the Sahara was a fertile landscape of lakes, rivers and savannah. The people who lived in the Tassili plateau left one of the world’s greatest archives of rock art: paintings and engravings showing round-headed figures (the oldest, circa 10,000 BC), cattle herders with their animals, hunters with bows, horses and chariots, and finally camels — documenting millennia of changing life and climate in the Sahara.
French ethnographer and explorer Henri Lhote first systematically recorded the art in 1956–1957, tracing and photographing thousands of images that had been unknown to the outside world. The scale and quality of the finds astonished the archaeological community. UNESCO inscribed Tassili n’Ajjer in 1982 as a site of outstanding universal value for both its rock art and its remarkable geology — an eroded sandstone landscape of natural arches, towers and forests of stone.
What you see
The Tassili plateau is a labyrinth of eroded sandstone formations: natural arches, isolated pinnacles, deep gorges and flat-topped mesas in shades of ochre, orange and deep red. Among the rocks, hidden in sheltered locations, are the paintings and engravings: some nearly life-size figures of animals long gone from the Sahara; cattle and herders; running figures; abstract symbols.
The landscape itself is spectacular even without the art — a high-altitude desert of surreal geological forms. Some cypress trees (Cupressus dupreziana), relics of the Sahara’s wetter past and among the world’s most endangered trees, survive in isolated groves on the plateau.
Practical information
- Base: Djanet, a town in south-eastern Algeria (served by flights from Algiers)
- Guides: visits require an authorised guide and 4WD transport; Tuareg guides are the most knowledgeable
- Best time: October to April; summers are dangerously hot (above 50°C)
- Caution: remote area; requires advance planning, permits and logistics
Getting there
The gateway is Djanet in south-eastern Algeria (IATA: DJG), reached by domestic flights from Algiers. From Djanet, excursions into the Tassili plateau require 4WD vehicles and a registered Tuareg guide. Advance permits from the Algerian authorities are required. GPS (centre): 25.50° N, 9.00° E.
